I'm all for niche content but BLU is more in the Verminion category of wasted resources. The number of players with the Morbol mount (sub 0.1%) definitely isn't proportional to the development time put into it.

I feel they just took the wrong direction with it. Limited class was a chance to break the shackles of design limitations and make something completely OP with a wide range of varied abilities. Instead, they backed themselves into a corner with the Carnival and Alex Savage into making a fully balanced class where most of the abilities aren't varied at all, but just elemental potency nukes, weak status debuffs and clunky cast bars as tank. I can understand some people like BLU, but it could have been so much more.

Making BLU a real job wouldn't really make it that exciting more than restricting it even further. It's just a failed idea sadly. They should keep it as it is for those who enjoy it, but personally I'd rather they cut their losses for the future. I'd be a little annoyed if we lost our HoH/PotD, Hildebrand chain and a dungeon per patch, but then they waste their time on 70 BLU content for the 0.1% who stick to it.
